I've had mine for 5 years. Works great on my wood stove. I just put a shelf on my buddy heater and now I use the fan on the buddy heater and it works great as well.
I had a tiny electric heater that couldnt heat up the room . I had a box fan and put it behind forcing more air. And the room is toasty. It literally went from being like a fridge to nice and warm so take what you will from that.
Adding to the comment below, they work via a component called 'Peltier' plates. When you apply power to the two wires it will heat one side and cool the other OR you can switch that around and HEAT one side of the plate and it generates power to, in this case drive a small motor.. and yes you can get and make these into phone chargers you place onto a hot surface (there are numerous YT vids on how-to) pretty neat!
After using one for about five years, I'm skeptical they improve heating, at least in our small, open-plan house. Often times the place seems warmer throughout without the fan. My suspicion is that the fan may be cooling off the top of the stove, which is supposed to get very hot and radiate. Can't prove that. As another observed, I agree that a ceiling fan has a greater impact, forcing heat down and around.
I have found out from my personal experience that a slow moving Ceiling fan works best. I have 4 oil lanterns that I use with my Ceiling fan and the Ceiling fan circulates the heat from the 4 oil lanterns very well and I'm talking about a medium size 19ft x 14ft room roughly with the door entrance cracked open about 1 inch for ventilation. The Ceiling fan also does even better on extremely sub freezing temperature days when using my kerosene heater and entrance door cracked slight open for ventilation.
Remember, in the winter, pull warmer air up. In the summer, reverse the fan and push the air down. If you try to push hot air down, against its natural tendency to rise, it will take more work and results in cooling the air. It looks to me like you've got bricks stacked right up against the back of the stove. If that's true, don't do that. You need air surrounding the stove, so that it can be heated and rise. Don't restrict it.
@@RoastBeefQueefSniffer funny how he’s telling the truth and will help the efficiency of that wood stove. Especially in their environment! All while you make stupid comments that match your really stupid handle.
@@oldrango883 Aww, look at how mad you are! That's a lot to get out of a four word comment, especially when I was being thankful as I'm buying a stove. You should probably go to a therapist bud.
Hi, we live off grid. Cold winters. On those very cold days/nights we open the stove door placing a wood stove screen over the front. Now the heat comes into the room more instead of all going out the pipe. Oh, our fan works great any place on the top, think ours is one size up from what yours are. I was always told don’t use rocks or bricks with the wood stove because they explode? Anyone else hear that? I really enjoy your videos, never lose your excitement and joy in what you are doing. Be safe, be well.
Pockets of h2O within the structure will expand and explode the containing vehicle. Thus it was always fun to throw "stream rocks" into an open fire and wait until the massive explosion, sending hot rock chips into the air so we could dodge them - hopefully.
Since it’s a old house just for the winters I would put plastic over the windows to try and keep cold air out . That’s what my grandmother would do every winter then take it off during summer .
@@Paul-hy3cu Yes it does. The best placement of the fan(s) are just behind the exhaust pipe--pointing towards to pipe. The pipe gets extremely hot and thus you want to utilize as much heat from the stove and exhaust pipe as possible.
You want to move the cold air towards the hot air, place it blowing towards the exhaust pipe. And any other fans in cold rooms blowing the air towards the stove.
lmao..... the more "potiential difference" there is between the bottom of fan(heat) & the cooling fins(cool) will cause the fan to rotate faster until it reaches it max RPM . so the fan placed offset to the right or left of the flue pipe at the rear or the firebox will be more likely to catch cooler air in its cooling fins . there is a thermal conductor at the cooling side & one under the foot of the fan base on the heating side.. the more difference between hot & cold will increase the "potiential difference" which is electricity. also the fans wont make any temps go up or down. the law of thermodynamics states [heat moves toward cold] so the fans are only helping move the heat that is produced by your heater farther away & warming more of the ambient air. if you want a hotter room you have to build a hotter fire... but if you give your room time to aclimate to the temp. of your heater (which will be faster with fans) the thermal heat will make the air a lot more comfy....and give more time for the radiant heat to heat the walls, floor, objects, ect.. and it will be time to party !
Our ( I actually put my by accident) but anyhow, we have got our new fire place luckily with enough room above the stove too put a fan on top of OUR new eco stove.. Cant wait too see if it works... I said my at first because I'm in charge of maintenance, glass cleaning emptying Ash out and find the wood.. But I find a stove therapeutic in so many ways.. ❤️ Thanks for sharing..
Several other people have already pointed out that the fans work best at the back of the stove. The principal of the operation is a bimetal element at the bottom that functions by the temperature differential between the bottom being heated and cooling the top side via the cooling ribs above it! Place the fan on the perimeter of the stove directing it towards the centre will give the best results.
It’s not the bi metal that is generating the power it’s the peltier element in between the cooling fins and the stand. The bi metal curls up when the bottom gets too hot. This way it’s protecting the peltier element
They defintely do aid in circulating the warm air , IMO their main strength is after initial start up . I think they make heating a room up happen slightly faster , and as they cost nothing to run its a result .
Yeah, this but it's probably also a bit more efficient in using the heat that is given by the stove itself. the device get's hot and that heat is throw into the room (so basically heating the air), it does not have to spin that fast imho.
I'm going to purchase one of these fans, my home is well insulated and the wood burning fireplace insert has hot air outflow venting in which I can set the fan above this vent to push that already hot air better through the room.
I dunno if it works or not. Mine never spins that fast, but it spins at a good rate. I mostly use it to judge if the fire is hot enough or not from across the room. Slow spin, add wood. Fast spin it's ok. As someone else mentioned, they seem to be effective in helping dry out wood on top of your stove. I always have a few pieces drying up there.
The fans aren’t supposed to blow hot air. People think they aren’t working because they are blowing cold air. Their purpose is circulating the heat from the stove not blowing hot air. If you are thinking of something that blows hot air then that would be a kerosene heater
Any time you move air, you cool it. Hot air rises where it will then stay close to the ceiling before cooling enough to fall down towards the floor, before being heated enough to rise again. One way to work with the natural convection cycle is to have a slow spinning ceiling fan that will encourage the hot air to get to the ceiling faster. That will push the hot air that is already there down towards the floor which should be warmer than what would fall naturally. It works better with smooth ceilings, as beams in the ceiling tend to make air dams that limit the hot air spreading across the room. The other thing you can do is to make sure that the fire box gets it's combustion air from an outside vent. Otherwise the fire box is using your heated air from inside the house and throwing it up the chimney. Lastly, in the room you want to be the most comfortable in, you need to insulate the outside wall. Brick walls will absorb a lot of your heat. It will absorb more heat than you could ever put into it. Unless your brick wall is facing a southern exposure where you can turn them into a solar collection wall, it's best to insulate them. You can do that with rigid insulation glued to the brick wall and then lathed and plastered over the insulation or you can frame a 2 X 4 wall in front of it and then insulate it normally. Remember 30% of your heat is lost through the ceiling. The more insulation up there the better off you'll be. The next big heat loss is through doors and windows, about 20%. Then it gets lost through the walls. The floors also remove heat, but the way you did your floors should pretty much limit that loss. We all know that heat radiates, but then, so does cold. Try closing your eyes and stand in the middle of the room. Hold your palm up and wet it. Then slowly turn around and just by the cold you feel on your palm you should be able to tell when you're facing the outside wall. Now walk toward it and as you get closer, you should feel the cold even more. Then turn around and face the inside of the room, your palm will feel warmer. Insulating the outside wall will create the thermal break needed to stop that cold from radiating into the house.
Fans do not actually lower the temperature of a room. They function by circulating air, creating a wind-chill effect on your skin which makes the room feel cooler than it actually is. The movement of air increases the rate of evaporation of sweat from your skin, thereby giving a cooling sensation. However, if you have ten fans in a small, closed room, they would not decrease the room's actual temperature. They would simply circulate the existing air, making it FEEL cooler if you're present in the room. If no one is in the room to perceive the wind chill, then the fans are essentially just circulating air without having any impact on temperature or perceived coolness.
I paid $200 for mine and I've also seen about 20 of these at various friends' cabins, and unfortunately they don't blow very much at all. The concept is great but in reality they barely move much air at all. To see it push a piece of paper you have to hold the sheet of paper basically right in front of the fan.
I agree. I don't think they are anything more than a gimmick. You need an electric fan to blow across the top of the stove or better yet.. a ceiling fan nearby the stove and one in your coldest room.
They're not design to blow air like a normal fan, however they do speed up air circulation in the room compared to not having one, so the heat distributes better.
I have had an ecofan for 15 years. It definitely makes a difference, puts air into the adjacent room through a wide passageway. I can tell because the thermostat is in that room and the central heat (for the other rooms) doesn't come on as often. Only problem mine has become very noisy...
It sounds like you do a little something everyday to stop the heat from escaping. Eventually you will get to where you need to be. Hopefully spring will arrive there soon and the cold won't be a problem.
I believe the thermometer works better in two places, right at the top of the stove, so you will know if stove is too hot, and above the battle so you know if the temp is too low or too hot. This way you control for the stove not overheating, and above battle you can close the battle and see if the temp is changing. What we want to avoid is burn the house or create creosote what will eventually also burn the house. I went ahead and just got two thermometers and use in both spots, make sure to compare it to a laser hand held thermometer to see the accuracy of the magnet ones
One of the most effective fans I've seen are those that are built into the stove itself. It takes the heat from around the fire box itself. They are often part of what's called zero clearance fire places. Another good fan is one that is built into the stove pipe itself. it can be bought separate and installs in the flue pipe. But be aware that that type of fan is efficient enough to actually cool the escaping smoke going up the chimney. This results in a need to clean the stove pipe of a bigger creosote build up that you wouldn't get if the escaping gases were hotter.
Yes, I agree. We've always had radiant heaters and ceiling fans to bring the heat down from the ceiling. We have a slightly bigger heater and it warmed a 12 metre by 8 metre space but our winters are quite moderate.
Haha your house looks like my house and you look like my partners son born. Thanks for info, i think i try them out cause cost is low and electricity is not needed.
I didn't read all the comments so I apologize if someone else is already said this. If you point the fans where they blow across your exhaust pipe they will dissipate more of the heat from the pipe into the room.
Convected heat rises whichever direction you blow it, so it all just ends up on the ceiling anyway along with the heat that rises directly above the fire, and as the moving efficiency of these fans is barely enough to push air a few inches, it goes nowhere but up. If you want heat directed horizontally across the room in a straight line however, you need to point the door glass in that direction and let radiation warm that cool corner or dry your laundry. But stoves are fixed, so whatever you want to heat has to be moved in line with the glass - or open door - instead.
Hi guys it was great seeing yous. Glad to see yous have fans now...once the walls have heat in them again it won't take long to heat up...it will take time. Maybe find a log company or find falling down trees and cut them for next year, as they will have to dry out...xxx
Dude, to get the most out of that stove you need another strongly built (wielded 1/4” steel) box above the stove with about 9, 2” steel tubes (again 1/4” or something close if you get stock in metric sizes) wielded horizontally…back to front. This reheater will capitalize on all of that heat going straight outside. Then put a fan sucking if mounted in front or blowing if mounted in back. This will actually overheat you brick structure such that you will have to install a variable intake limiter to reduce the fuel burn rate. Put it on legs so that the reheating box (with the tubes) is about 2.5’ above the stove top. This will drastically reduce your wood consumption and almost triple your heat output simultaneously. If you don’t wield neatly you could find a guy in your berg who can fab this up in about 2-3 hours. Then you just need to paint it with height temperature enamel from a rattle can and get some more stove pipe and reroute your exhaust. Best,
For whatever it’s worth. I have owned a Heritage Hearthstone soapstone stove for 18 years. The company claims 65% efficiency. I think that is marketing bullshit. I could have bought an attached fan for about $350 which rated poorly on reviews. My wife suggested taking a cheap table top fan ( which we already own) and point it at the stove. It was amazing. My basement living room, which barely got up to 70* now gets up to close to 80*. The warm air flows up the stairwell and keeps the main floor heated. More heat and less wood usage all because of pointing a room fan at the stove
I think what's more important than moving the air is pulling more energy from the exhaust pipe with a pipe mounted fan. So kire heat stays in the room.
If the stove is using the exterior wall existing chimney, a good portion of the heat is just heating up the outside wall. A more centrally located stove (not up against a wall), free standing with a chimney pipe going directly up through the roof is ideal. That stove is big enough. Being centrally located (all sides exposed to the room), it would work well. Right now, it's just heating up an exterior wall ...like a traditional fireplace.
Lol you want to charge your phone from the fire I suggest purchasing a BioLite stove it's got a thermocoupler built into it to turn the fire into electricity , nice fans though use them in my hot tent for winter camping, don't put them Ever in front of the pipe though unless you want to turn them into trash lol .
Correct. I have been using mine 13 years and it is great. The pile of bricks behind this stove is 100% wrong. They stifle air movement. The cold air rising behind is essential for these fans to work correctly.
Hi, thanks for the video, I hope the weather starts to warm up soon. I missed my regular dose of my favourite farmily. I will look forward to your vlog tomorrow :-)
I have found these fans to be useful for one thing.. quickly drying wood that has snow/ice on it. I place the wood on top of firebrick, on top of the stove and point that fan at it. Outside of 18" I think there pretty useless.
I have a couple similar fans that clamp onto the chimney pipe so the top of my stove is clear for a pot of water the fans help move the heat pretty nice
I have 1 fan on my Morso 06 stove. I would say probably at least15% improvement. However these fans arent super-reliable and I had to buy a new Pelltier device for mine after 18 months and also the motor had stiffened up and needed some penetrating lube to get it going properly again.
First let me say I love your music. Number one mistake people make when installing wood stove pipe, do not turn pipes out thru wall. Lots of heat comes from the chimney pipe. and you get much less creosotes in a straight chimney out. Also if you burn real hot every so often it will burn all the creosote regularly and no need to clean chimney pipes. With chimney pipe straight and a low speed ceiling fan you get a whole house warm perfectly
As someone else has said bricks at the rear of the stove isn't good as the hot air can't radiate from there, also all the brickwork acts like a heat sink good insulation is a must
I have a large cooking/surface area on my wood burning stove. I put it in the middle and not towards the back because these fans don't really have any strength. It's kind of a waste. I've even put on of them at the entrance of the stove facing in, to see if I can get the fire hotter. It didn't work AT ALL.
I see you have piles of bricks on one side and at the rear this prevents convection (rising air) all sides should be clear to get maximum heat from the burner.
I think the bricks are partly placed like little shelves and a log store. Some people put bricks against the stove to absorb heat and radiate it later after the fire goes out, but usually you just stoke it up to last through the night.
These fans are cool little science experiments for elementary or middle school kids. Great concept and would be awesome if they actually moved a CFM or even two! After buying one and using it for several days it made zero difference in time to heat a space and zero difference in forward projection of heat. On the other hand it is fun to watch the blades rotate.
You seem to have a double-walled chimney pipe. that thermometers don't work on those. Put it instead on the flat top. For the double-walled pipe, you need type where you drill holes and put in probe stick inside about 12 inches up from stovetop.
they are perfect as a passive heat sink/delivery - their job is literally to absorb and reflect heat into a convective force. I never knew this thing existed until now!
I know the door to the hallways is lacking but still there sould be more warmt. I had a woodcabin. It was so cold there but the stove really did the trick. it was not isollated at all, neither walls, floors or roof. The floors was just levels of planks. Still be got it to 27 degrees wich was again too hot.
no fans are needed the heat from the stove circulates the air ! all you may need is a way to pull the cold air from the floor ! that will not heat unless it is circulated ! it is simple thermal dynamics people ( heat rises ? cold drops ? ) !
I use a power fan on my fire to blow cold air onto the fireplace and it works amazingly. The amount of heat lost out the chimney instead of heating the fireplace is crazy, so by having the fan blowing cool air towards the fire not only do you move more warm air around but the cold air is sacrificed to the chimney instead of the warm air around the fireplace
A lot of people say the fan works on the back side of the stove. This always isn't the case. The idea of the stove fan is to take cold air and push it over the hot areas thus warming the room more efficiently. My stove has a ledge in the back that is for cold air to pass over the firebox creating warmer air... The upper ledge is cooler than the lower ledge of the stove, making the fans less effective than if they were in a hotter area. I put the fans on the outer edge on the hotter lower front part of the stove, facing inwards pulling cold room air and pushing it over the hot stove.
The fan will by no means generate or get the oven to generate more heat. It will only circulate air in the room. The fan is meant to circulate the air in the room so you have a more uniform temperature throughout the room instead of hot air accumulating up under the roof and cold air at the floor where you are residing, mixing the hotter air from up under the roof with the colder air from the floor in order to get something in between both places. To test it, place two thermometers in the room, one 2 to 3 feet above the floor and the other one a foot below the roof and see whether using the fan will give more equal temperature. If it does get more equal with the fan than without, it works, if not, it does not work. Also have in mind that the fan gets its electricity to the fan motor from the difference in temperature between the fan's foot (absorbed from the stove) and the cooling fins (cooled by the air drawn through the fan). It will therefore spin faster the hotter the oven is and the cooler air it sucks.
I am about to get one but would say that they have to work in theory just by the fact they move the air. Without a fan a lot of the heat will rise into the chimney. It is a question of spreading the heat.
use more horizontal iron tubes for the chimney it will do magic urs is just losing over 50% to the outside the hot smoke is the key u don't need fans as a rule for every vertical pipe u can have 4 horizontal and try to give them angels u get way more than that with angels
They work great if you expect them to do what they were made to do. But if you’re expecting them to make the room warmer than the wood stove is able to without them, you’re kidding yourself. They direct heat to cooler areas of the room, they help direct heat to where you are drying things, laundry or wet winterwear, foods, etc.
There are many places that give the pallets away for free but too many people struggle for wood and they are taken before we could even ask, next year we will hopefully get a load of wood so will not have to worry 😊❤️
Would that fan work if a person set of a heat source from a set of "tea lights"? Could you to a test run to see how many tea lights it would take to generate adequate heat? This might be a good item for those in Europe to use this upcoming winter when their heating fuel will be diminished!
One candle gives out approximately 30 Watts of heat energy. If a 1000 watt electric heater (1kw) heats the room enough, then thirty three good tealight candles should also heat that same room. Those terracotta pot/candle heaters are good at collecting/storing heat to radiate it, especially if you're sitting close to one, they prevent the heat from rising straight to the ceiling. Unfortunately tealight candles aren't that cost effective when so many are needed. I found (over the years) that pretty much all energy is priced accordingly... per kW. I think it's more about efficiency than what source we use; how we use that energy, A Clark.
You guys should build a rocket mass heater, they get much hotter than conventional wood stoves and use a fraction of the wood. The "batch box" rocket mass heater is the latest design
Not any more than your current stove. A rocket mass heater stores the heat in dense rocks and/or clay, and slowly release the heat over many hours or days, even after the fire has gone out Most of the heat from your stove, or a traditional fireplace goes right out of the chimney and is lost. You are losing the vast majority of the heat out of your chimney (heating the air outside). Rocket mass heaters are the most efficient heaters you can have, because virtually no heat is lost to the outside
I've had mine for 5 years. Works great on my wood stove. I just put a shelf on my buddy heater and now I use the fan on the buddy heater and it works great as well.

That depends on the type of rock or brick. As @franciskelly mentioned. Lava rocks and I think maybe most insigneous rocks won't explode.
You can buy fire brick for this or mold bricks from a specific type of firesafe cement. A lot of people have done this to make outdoor pizza ovens.

It doesn't matter if they are in front as they will pull the hot air through the blades rather than push it. Hope this helps.

Now walk toward it and as you get closer, you should feel the cold even more. Then turn around and face the inside of the room, your palm will feel warmer.
Insulating the outside wall will create the thermal break needed to stop that cold from radiating into the house.
"Any time you move air, you cool it." This is 100% incorrect!!
It’s not the cold air falling, it’s the warm air rising.
Fans do not actually lower the temperature of a room. They function by circulating air, creating a wind-chill effect on your skin which makes the room feel cooler than it actually is. The movement of air increases the rate of evaporation of sweat from your skin, thereby giving a cooling sensation. However, if you have ten fans in a small, closed room, they would not decrease the room's actual temperature. They would simply circulate the existing air, making it FEEL cooler if you're present in the room. If no one is in the room to perceive the wind chill, then the fans are essentially just circulating air without having any impact on temperature or perceived coolness.
I paid $200 for mine and I've also seen about 20 of these at various friends' cabins, and unfortunately they don't blow very much at all. The concept is great but in reality they barely move much air at all. To see it push a piece of paper you have to hold the sheet of paper basically right in front of the fan.
I agree. I don't think they are anything more than a gimmick. You need an electric fan to blow across the top of the stove or better yet.. a ceiling fan nearby the stove and one in your coldest room.
They're not design to blow air like a normal fan, however they do speed up air circulation in the room compared to not having one, so the heat distributes better.
You paid $200 for a stove fan?
@@robbieshaft yeah, they used to be a specialty item, but since then the good ones have gone down to around $100 each.
I have had an ecofan for 15 years. It definitely makes a difference, puts air into the adjacent room through a wide passageway. I can tell because the thermostat is in that room and the central heat (for the other rooms) doesn't come on as often. Only problem mine has become very noisy...
It sounds like you do a little something everyday to stop the heat from escaping. Eventually you will get to where you need to be. Hopefully spring will arrive there soon and the cold won't be a problem.
Yeah spring is around the corner 😊❤️
I believe the thermometer works better in two places, right at the top of the stove, so you will know if stove is too hot, and above the battle so you know if the temp is too low or too hot. This way you control for the stove not overheating, and above battle you can close the battle and see if the temp is changing. What we want to avoid is burn the house or create creosote what will eventually also burn the house. I went ahead and just got two thermometers and use in both spots, make sure to compare it to a laser hand held thermometer to see the accuracy of the magnet ones
One of the most effective fans I've seen are those that are built into the stove itself. It takes the heat from around the fire box itself. They are often part of what's called zero clearance fire places. Another good fan is one that is built into the stove pipe itself. it can be bought separate and installs in the flue pipe. But be aware that that type of fan is efficient enough to actually cool the escaping smoke going up the chimney. This results in a need to clean the stove pipe of a bigger creosote build up that you wouldn't get if the escaping gases were hotter.
You need to get a couple of ceiling fans to move the hot air from the ceiling and get everything warm.
Yes, I agree. We've always had radiant heaters and ceiling fans to bring the heat down from the ceiling. We have a slightly bigger heater and it warmed a 12 metre by 8 metre space but our winters are quite moderate.
@@williamwallace9620 My living room fan is almost right above my wood stove. Just switch it to reverse, warms up my whole living room!
You can trim your nails on the fans as an added bonus
Haha your house looks like my house and you look like my partners son born. Thanks for info, i think i try them out cause cost is low and electricity is not needed.
I put a powerful 12 inch mains fan pointed at the stove, it heats the room better than without, its a strong fan mind.
I didn't read all the comments so I apologize if someone else is already said this. If you point the fans where they blow across your exhaust pipe they will dissipate more of the heat from the pipe into the room.
For sure 👍🏻
Yeah a cheap box fan aimed at the stove is quite effective.
@@tomkitchen9457 that takes electricity bruh
Convected heat rises whichever direction you blow it, so it all just ends up on the ceiling anyway along with the heat that rises directly above the fire, and as the moving efficiency of these fans is barely enough to push air a few inches, it goes nowhere but up. If you want heat directed horizontally across the room in a straight line however, you need to point the door glass in that direction and let radiation warm that cool corner or dry your laundry. But stoves are fixed, so whatever you want to heat has to be moved in line with the glass - or open door - instead.
We use a ceiling fan really helps warm the room.
In the late 1800s they had chistmas decorations that were made from brass that moved from heat of small candells .
Yup, they are still around. Search for "candle carousel".
Hi guys it was great seeing yous. Glad to see yous have fans now...once the walls have heat in them again it won't take long to heat up...it will take time. Maybe find a log company or find falling down trees and cut them for next year, as they will have to dry out...xxx
Thank you! 😊❤️ We will find some wood in spring now so it can dry out for next season! 😁
@@DoBeDiff I guys i sent yous a message on Instagram just because I was worried about yous...from Scotland xx
Dude, to get the most out of that stove you need another strongly built (wielded 1/4” steel) box above the stove with about 9, 2” steel tubes (again 1/4” or something close if you get stock in metric sizes) wielded horizontally…back to front. This reheater will capitalize on all of that heat going straight outside.
Then put a fan sucking if mounted in front or blowing if mounted in back. This will actually overheat you brick structure such that you will have to install a variable intake limiter to reduce the fuel burn rate.
Put it on legs so that the reheating box (with the tubes) is about 2.5’ above the stove top.
This will drastically reduce your wood consumption and almost triple your heat output simultaneously.
If you don’t wield neatly you could find a guy in your berg who can fab this up in about 2-3 hours. Then you just need to paint it with height temperature enamel from a rattle can and get some more stove pipe and reroute your exhaust.
Best,
Sure, let me just gather up all of the materials and welder and whip it right up
do you have an image or example of this?
For whatever it’s worth. I have owned a Heritage Hearthstone soapstone stove for 18 years. The company claims 65% efficiency. I think that is marketing bullshit. I could have bought an attached fan for about $350 which rated poorly on reviews. My wife suggested taking a cheap table top fan ( which we already own) and point it at the stove. It was amazing. My basement living room, which barely got up to 70* now gets up to close to 80*. The warm air flows up the stairwell and keeps the main floor heated. More heat and less wood usage all because of pointing a room fan at the stove
How abut putting a cheapo box fan at the most distant line-of-sight place down the hallway and aim it at the stove. Quickest heat mixing location
Genius
I think what's more important than moving the air is pulling more energy from the exhaust pipe with a pipe mounted fan. So kire heat stays in the room.
They definitely work, I have two of them 👍🏻👍🏻👍🏻
I think it's more of a conversation piece than anything
If the stove is using the exterior wall existing chimney, a good portion of the heat is just heating up the outside wall. A more centrally located stove (not up against a wall), free standing with a chimney pipe going directly up through the roof is ideal. That stove is big enough. Being centrally located (all sides exposed to the room), it would work well. Right now, it's just heating up an exterior wall ...like a traditional fireplace.
But they have double brick walls with the air space between so that make a diferentes.
and your point is?
@@gryphonennis1002 If you've ever relied solely on wood stove heat, this wouldn't perplex you.
With or without the faens. Did you feel anything at all ? Now thinking about the pread of the heat.
We have one of those little fans, it works greats, we also have ceiling fans.
Lol you want to charge your phone from the fire I suggest purchasing a BioLite stove it's got a thermocoupler built into it to turn the fire into electricity , nice fans though use them in my hot tent for winter camping, don't put them Ever in front of the pipe though unless you want to turn them into trash lol .
We also want to buy one and I did some research on it and found that it is better to place it behind / next to the pipe, not in front of it.
Thank yoi for the info, I will try that, I was moving around to see where its better 😊❤️
@@DoBeDiff hope it works! We first have to check if there will be enough space as our woodstove is a bit smaller than yours.
@@BrendaLelie they are quite small! Should be no problem, like 5cm in width! 🤔
Correct. I have been using mine 13 years and it is great. The pile of bricks behind this stove is 100% wrong. They stifle air movement. The cold air rising behind is essential for these fans to work correctly.
there is a little tiny camp stove, like heat 1 cup of water small, that you heat w wood and you can charge your phone,
looking forward to the video you're making.
Thank you! 😊❤️
These fans really help to eliminate the cool spot often felt at floor level . They don’t blow in my opinion the just circulate the warm air .
Dont even have a wood stove or fire place. Not sure why I watched this video but it was cool
As long as the walls are not insulated, it is normal not to have enough heat. And anyway the stove is too small for a kitchen and a living room.
Hi, thanks for the video, I hope the weather starts to warm up soon. I missed my regular dose of my
favourite farmily. I will look forward to your vlog tomorrow :-)
Thank you! 😊❤️
I have found these fans to be useful for one thing.. quickly drying wood that has snow/ice on it. I place the wood on top of firebrick, on top of the stove and point that fan at it. Outside of 18" I think there pretty useless.
Should point them at the chimney to blow the heat off it and into the room. The chimney pipe is on it's way to taking heat out of the house anyway.
Hang up a blanket by your leaky door. That will stop a lot of wind from coming through.
I'm looking at these for passive cooling for my supercharger between races 😅
I have a couple similar fans that clamp onto the chimney pipe so the top of my stove is clear for a pot of water the fans help move the heat pretty nice
I got them from a store called Princess Auto I'm not sure where you live but we have those stores in Canada
Will purchase again. I have always trusted the Lasko brand.
I have 1 fan on my Morso 06 stove. I would say probably at least15% improvement. However these fans arent super-reliable and I had to buy a new Pelltier device for mine after 18 months and also the motor had stiffened up and needed some penetrating lube to get it going properly again.
First thing I noticed too was that they should point at the HOT stovepipe and blow acrost it.
They work far better on a wood burning stove instead of a wood fire place. Insulation works both ways for keeping heat in or out.
First let me say I love your music.
Number one mistake people make when installing wood stove pipe, do not turn pipes out thru wall.
Lots of heat comes from the chimney pipe. and you get much less creosotes in a straight chimney out.
Also if you burn real hot every so often it will burn all the creosote regularly and no need to clean chimney pipes.
With chimney pipe straight and a low speed ceiling fan you get a whole house warm perfectly
It's a good idea however if u adjust air and clean out all the bits and Bob's then open door heat will rise increasing in front of fan maybe..
Want to watch all your series but don’t know what sequence they come in . I would like to start at No 1 the beginning and work through xx
Here is the playlist from the beginning just skip what you already watched 😊❤️: ua-cam.com/play/PL_NOQIOI8_jFtfg-okg5vcFANi_T-kCBH.html
For phone charging all you need is a small solar panel. Cheaper that those motors.
The heat comes from the glas point them outwards so the heat blows from glas to the middle of room
I have one. These are to look at and admire. They do nothing to improve your home's heat distribution. A big ceiling fan is the way to go.
When I use a fan with the wood burner, I point it at the flue.
As someone else has said bricks at the rear of the stove isn't good as the hot air can't radiate from there, also all the brickwork acts like a heat sink good insulation is a must
My fan info says to put the fans towards the rear of the stove.
Good luck.
Cold air or hot air
Yes put back more if your gona cook on top. But it looks nice.
I have a large cooking/surface area on my wood burning stove. I put it in the middle and not towards the back because these fans don't really have any strength. It's kind of a waste. I've even put on of them at the entrance of the stove facing in, to see if I can get the fire hotter. It didn't work AT ALL.
Just happy your warmer !
Thank you! 😊❤️
I see you have piles of bricks on one side and at the rear this prevents convection (rising air) all sides should be clear to get maximum heat from the burner.
I think the bricks are partly placed like little shelves and a log store. Some people put bricks against the stove to absorb heat and radiate it later after the fire goes out, but usually you just stoke it up to last through the night.
These fans are cool little science experiments for elementary or middle school kids. Great concept and would be awesome if they actually moved a CFM or even two! After buying one and using it for several days it made zero difference in time to heat a space and zero difference in forward projection of heat. On the other hand it is fun to watch the blades rotate.
You seem to have a double-walled chimney pipe. that thermometers don't work on those. Put it instead on the flat top. For the double-walled pipe, you need type where you drill holes and put in probe stick inside about 12 inches up from stovetop.
they are perfect as a passive heat sink/delivery - their job is literally to absorb and reflect heat into a convective force. I never knew this thing existed until now!
I have a twin rota fan and it certainly does work.
OO...that's a cold shack. Happy to have a small shack.
You need outside combustion air, that stove suck all the heat out the chimney through the air intake that's from your room
I know the door to the hallways is lacking but still there sould be more warmt. I had a woodcabin. It was so cold there but the stove really did the trick. it was not isollated at all, neither walls, floors or roof. The floors was just levels of planks. Still be got it to 27 degrees wich was again too hot.
no fans are needed the heat from the stove circulates the air ! all you may need is a way to pull the cold air from the floor ! that will not heat unless it is circulated ! it is simple thermal dynamics people ( heat rises ? cold drops ? ) !
I use a power fan on my fire to blow cold air onto the fireplace and it works amazingly. The amount of heat lost out the chimney instead of heating the fireplace is crazy, so by having the fan blowing cool air towards the fire not only do you move more warm air around but the cold air is sacrificed to the chimney instead of the warm air around the fireplace
A lot of people say the fan works on the back side of the stove. This always isn't the case. The idea of the stove fan is to take cold air and push it over the hot areas thus warming the room more efficiently. My stove has a ledge in the back that is for cold air to pass over the firebox creating warmer air... The upper ledge is cooler than the lower ledge of the stove, making the fans less effective than if they were in a hotter area. I put the fans on the outer edge on the hotter lower front part of the stove, facing inwards pulling cold room air and pushing it over the hot stove.
That may work I will try this
The fan will by no means generate or get the oven to generate more heat. It will only circulate air in the room. The fan is meant to circulate the air in the room so you have a more uniform temperature throughout the room instead of hot air accumulating up under the roof and cold air at the floor where you are residing, mixing the hotter air from up under the roof with the colder air from the floor in order to get something in between both places. To test it, place two thermometers in the room, one 2 to 3 feet above the floor and the other one a foot below the roof and see whether using the fan will give more equal temperature. If it does get more equal with the fan than without, it works, if not, it does not work. Also have in mind that the fan gets its electricity to the fan motor from the difference in temperature between the fan's foot (absorbed from the stove) and the cooling fins (cooled by the air drawn through the fan). It will therefore spin faster the hotter the oven is and the cooler air it sucks.
I have one. Found it causes chimney to stop up frequently. So I don't use it anymore.
Tape plastic over your windows and get sealing strips for your doors
I am about to get one but would say that they have to work in theory just by the fact they move the air. Without a fan a lot of the heat will rise into the chimney. It is a question of spreading the heat.
Hahaha I mean it in a good way you and your family stay safe
In response to the last comment , I think your right, you’d think he’d do a little research first, I’m buying one anyway not due to the review. Lol
Anyone that owns one knows the answer to that love mine at those temperatures it’s going to be a couple of days before the room is comfortable
use more horizontal iron tubes for the chimney it will do magic urs is just losing over 50% to the outside the hot smoke is the key u don't need fans as a rule for every vertical pipe u can have 4 horizontal and try to give them angels u get way more than that with angels
I really hoped for a proper review but all I got was daft music noise.
59°F and you're using stove?
That's short sleeve weather, great temp to work outside here...lol
They work great if you expect them to do what they were made to do.
But if you’re expecting them to make the room warmer than the wood stove is able to without them, you’re kidding yourself.
They direct heat to cooler areas of the room, they help direct heat to where you are drying things, laundry or wet winterwear, foods, etc.
I've read you put those in the back of the stove.
The instructions on mines says to put them behind (not the stove) closer to the pipe
Yeah they work better, but I have no space behind the pipe! 😁❤️
Hope you are staying warm
@@DoBeDiff SO put them as far back as possible and point them towards the exhaust pipe.
You should start your fire in the morning en this for several days, the bricks/walls will warm up en you will be kozy :) greetings from Belgium
Yeah that would definitely help! We don't have much wood or money to burn much more so for now we will just keep the bedroom warm ❤️😊
@@DoBeDiff When you are going to the city, try to find some free pallets, are there some woodmills in your region ? you can also ask them :)
There are many places that give the pallets away for free but too many people struggle for wood and they are taken before we could even ask, next year we will hopefully get a load of wood so will not have to worry 😊❤️
1:20 you might want to get several thermometers and put them in different locations on the stove
Love watching you all! What happened to the barrel stove? I missed that episode. The new stove looks great!
Put a tarp in front of the door with a board to hold In place.
This is definitely red dead music. Lol. Thanks for the video.
Would that fan work if a person set of a heat source from a set of "tea lights"?
Could you to a test run to see how many tea lights it would take to generate adequate heat?
This might be a good item for those in Europe to use this upcoming winter when their heating fuel will be diminished!
One candle gives out approximately 30 Watts of heat energy. If a 1000 watt electric heater (1kw) heats the room enough, then thirty three good tealight candles should also heat that same room.
Those terracotta pot/candle heaters are good at collecting/storing heat to radiate it, especially if you're sitting close to one, they prevent the heat from rising straight to the ceiling.
Unfortunately tealight candles aren't that cost effective when so many are needed.
I found (over the years) that pretty much all energy is priced accordingly... per kW.
I think it's more about efficiency than what source we use; how we use that energy, A Clark.
You guys should build a rocket mass heater, they get much hotter than conventional wood stoves and use a fraction of the wood. The "batch box" rocket mass heater is the latest design
And you have to feed them constantly
Not any more than your current stove. A rocket mass heater stores the heat in dense rocks and/or clay, and slowly release the heat over many hours or days, even after the fire has gone out
Most of the heat from your stove, or a traditional fireplace goes right out of the chimney and is lost. You are losing the vast majority of the heat out of your chimney (heating the air outside).
Rocket mass heaters are the most efficient heaters you can have, because virtually no heat is lost to the outside
